How is a roof leak found and fixed?
Leak detection is a process of elimination. The inspector starts inside, looking at ceiling stains, attic framing and insulation for water trails. Then the roof surface above the area is checked, along with every penetration and joint nearby.
Repairs usually fall into a few groups.
Tile roofs
Broken tile is replaced, loose tile is reset, and failed flashing or sealant is redone. Finding a tile that matches the old color and profile can take time.
Shingle roofs
Damaged shingles are replaced, exposed nails are sealed or corrected, and flashing and vent boots are renewed.
Metal and low-slope roofs
Fasteners, seams and sealant are checked and redone. Low-slope areas are checked for ponding and open seams.
If a repair is only a patch on an aging roof, you should hear that plainly, along with the option of a full roof replacement.
